Palsas is an own rare type of nature occuring around permafrost land. Because of the warming climate, the palsas are melting and disappearing many places. In this webinar I will tell you why that may have consequences in the subarctic region and what the palsas tell us.

Palsas are created at mires covered with peat. It consists of a frozen core of ground material and water covered by peat soil. The peat insulate the palsas so they do not melt in the summer. The core of the palsa is a permanently frozen but will change size and shape through time as the palsas respond to changes in climate, the direction of the wind how and when the rain and snow is falling etc. Enrol and learn why such a rare nature type can be an important climate indicator.
